ABSTRACT

A pivotable folding utility table includes a table top having a pair of support pedestals pivotally attached thereto. A first pivotal support brace including a distal end and a proximal end attached to the first support pedestal. A second pivotal support brace including a distal end and a proximal end attached to the second support pedestal. The distal ends of the first and second pivotal support braces pivotally attached to a retaining assembly preferably mounted in relation to the table top. Specifically, the retaining assembly includes a cross-brace member operably disposed through openings formed in the distal ends of the first and second pivotal support braces, thus providing a pivotal engagement in relation to the table top. Alternatively, a second retaining assembly including a cross-brace member may be mounted in relation to the table top, wherein the distal end of the first pivotal support brace pivotally engages the first retaining member and the distal end of the second pivotal support brace pivotally engages the second retaining member. In addition, the first and second support pedestals may comprise at least one support leg, wherein each support leg of the first and second support pedestals are laterally offset from each other so as to permit an offset displacement of the support legs when the support pedestals are disposed in a collapsed position.

BACKGROUND OF THE INVENTION

[0002] 1. The Field of the Invention

[0003] The present invention is related to a utility table, and moreparticularly, to a portable folding utility table having one or morecenter support assemblies and off-set support legs that selectivelysupport the utility table above a surface.

[0004] 2. Technical Background

[0005] Portable folding utility tables are indispensable for groups ororganizations that have limited floor space usable for multiplepurposes. For example, foldable utility tables can be placed in apre-determined configuration to meet the space requirements of a schoolgymnasium, a church multi-purpose room, or a hotel conference meetingroom. Afterward, the tables can be neatly stored away and the conferenceor meeting room used for a different purpose. Thus, portable foldingutility tables allow a group or organization to maximize the efficiencyand utility of a particular space.

[0006] Foldable utility tables can also provide an immediate temporarywork space in a garage, tool shed, and the like. The portability andfoldability of these utility tables allows a user to conveniently setup, take down, and store the table whenever and wherever the userchooses.

[0007] A major drawback with many portable folding utility tables of theprior art, however, is their inherent size and bulkiness. Many suchutility tables require two people to collapse and store the table afteruse. Moreover, some prior art portable folding utility tables are heavyenough to cause injury if dropped or mishandled. These unwieldy tablesare usually made from hardwood, particle board, or similarly heavymaterials. In an attempt to overcome this weight and bulkiness problem,some prior art portable utility tables are formed of lighter-weightmaterials. However, many of these lightweight utility tables generallylack the sturdiness of the heavier-weight prior art utility tables.

[0008] Another disadvantage to prior art utility tables is the meansused for attaching the table support legs or two or more supportpedestals to the underside of the table. As will be appreciated, priorart table support legs are typically attached to the table top usingthreaded screws or bolts that are drilled into the underside of thetable top. This means of attachment may compromise the integrity of thetable top thereby making it weaker at the point of attachment betweenthe table support legs and the table top. Other attachment mechanismsmay include a form of bonding the table support legs as supportpedestals directly against the surface of the table top. Often, however,this means of attachment by bonding weakens the structural integrity ofthe table top. Thus, when the table support legs fail, a portion of thematerial forming the table top may pull away at the point of the bondedattachment thereby making the table costly, if not impossible to repair.

[0009] In an attempt to overcome the foregoing disadvantages, prior artutility tables were developed by those skilled in the art that areequipped with complex or heavy-duty attachment mechanisms thatfacilitate a secure attachment between the table support legs or thesupport pedestals and the table top. These types of attachmentmechanisms, however, are normally heavier, more costly, more difficultto install, and typically require additional time to manufacture.

[0010] The previously stated disadvantages are compounded by the factthat many prior art utility tables incorporate a separate and distinctattachment mechanism for attaching each table support leg or pedestal tothe table top. As appreciated, most existing portable folding utilitytables have two sets of support legs or pedestal supports, one at eachend of the table. Each of these supports is typically attached to theunderside of the table top at two places or points of contact.Correspondingly, many of these types of utility tables have at leastfour separate points of attachment, each attachment between the supportlegs or pedestal supports facilitated by a separate attachmentmechanism. One particular problem with utility tables having separateand distinct attachment mechanisms is that they are generallysusceptible to bowing in the center of the table top under stress. Thisis especially true with larger banquet style tables.

[0011] Yet another drawback with many prior art utility tables is thatthe hard materials used to maintain a sufficient rigidity and sturdinessof the table top often have sharp edges which may be uncomfortable forthe user to lean against or rest their arms upon. Further, thesematerials may also be susceptible to damage or degradation from theelements of nature.

[0012] In addition, smaller utility tables that are found in the priorart usually comprise shortened support legs that fail to providesufficient height to the table top in relation to the underlyingsurface, thus these types of table are generally uncomfortable to users.In particular, when these prior art utility tables are configured in thefolded position for storage, the table support legs are required to beshort enough so not to interfere with each other when folded in aconventional fashion underneath the table top. Small folding utilitytables of the prior art are also typically bulky when disposed in thefolded position because complex and unwieldy mechanisms are generallyrequired to accommodate the use of longer support legs that may beincorporated to overcome the inherent height deficit found in mostsmaller utility tables.

[0013] From the foregoing, it will be appreciated that it would be anadvancement in the art to provide a portable folding utility table thatis durable enough to withstand the increased wear and tear that portableutility tables are subjected to over long periods of time and sturdyenough to support varying sized loads that will be placed on the table,while at the same time being light-weight enough to be easily set up andtaken down.

[0014] It would be another advancement in the art to provide a portablefolding utility table having a leg or support pedestal attachmentmechanism that does not involve a complex design, heavy duty attachmenthardware, or need to be screwed, bolted, or bonded to the under side ofthe table top. It would be a further advancement in the art to provide aportable folding utility table that minimizes the points of attachmentto the surface of the table top and facilitates attachment mechanismsthat interrelate with each other to support the table top above anunderlying surface.

[0015] Furthermore, it would be an advancement in the art to provide aportable folding utility table that may provide a smaller workingsurface than larger utility table, but that is comfortable to work at inrelation to its height disposition and which is capable of withstandingthe elements of nature.

[0016] Finally, it would be an advancement in the art to provide aportable folding utility table in which the support legs or pedestals,having a length greater than the corresponding length of the table top,can fold against the underside of the table top when disposed forstorage without interfering with each other, so that smaller frames andtable tops can be used that accommodate a sufficient height dispositionin relation to the underlying support surface.

[0017] Such a portable folding utility table is disclosed and claimedherein.

BRIEF SUMMARY OF THE INVENTION

[0018] The present invention is directed to a novel portable foldingutility table having a center support assembly. The utility tableincludes a table top supported by a pair of support pedestals. In onepresently preferred embodiment, the table top includes a mountingsurface and a working surface formed opposite the mounting surface. Theworking surface may be textured and may include an integral outerperiphery, at least a portion of which is beveled to provide comfort toa user.

[0019] A first end of each support pedestal is preferably attached tothe mounting surface of the table top. In one presently preferredembodiment, the support pedestals are pivotally attached to the mountingsurface of the table top, to allow each support pedestal to be movedbetween a collapsed position and an extended position for supporting thetable top above a surface. A securing member may also be attached to themounting surface for releasably securing one or more support pedestalsin the collapsed position.

[0020] Additionally, the utility table may include a first pivotingsupport brace attached to the first support pedestal at a proximal endand to the mounting surface at a distal end thereof. Similarly, a secondpivoting support brace may be attached to the second support pedestal ata proximal end and to the mounting surface at a distal end thereof. Inone presently preferred embodiment of the present invention, the distalends of the first and second pivotal support braces are disposedcontiguous to each other at a retention assembly attached to themounting surface or, in the alternative, to a support frame.

[0021] In one presently preferred embodiment of the present invention,the retention assembly may include a single cross-brace member disposedthrough openings formed at the distal ends of the pivotal support bracesand secured to the mounting surface. The mounting surface may beconfigured such that opposing ends of the cross-brace member areintroduced through openings disposed in opposing sides of the mountingsurface of the table top and may further include a mount for receivingand retaining the cross-brace member therein. Thus, the distal ends ofboth support pedestals are preferably attached along the length of thecross-brace member which is secured to the mounting surface, therebyreducing the number of attachment mechanisms and interrelating thesupport pedestals to the table top to increase structural support andefficiency of manufacture.

[0022] In another presently preferred embodiment, each support pedestalincludes a first member pivotally engaging the mounting surface of thetable top and a second member configured for telescoping engagement withthe first member. This configuration permits the height of the supportpedestal to be disposed between a lengthened position and a retractedposition.

[0023] In an alternative presently preferred embodiment, the table mayinclude two cross-brace members providing separate attachment points forthe first and second pivotal support braces. Such a configuration isparticularly desirable for tables having an extended length, in which itmay not be advantageous for each of the pivotal support braces to havelengths sufficient for extending into the center of the table top.Correspondingly, a dual cross-brace configuration may provide additionalspace for accommodating one or more user's legs under the table top.

[0024] Moreover, in yet another presently preferred embodiment of thepresent invention, each support pedestal may include two legs slightlyoffset from the corresponding legs of the other support pedestaldisposed on the opposing side of the table top, so that longer supportlegs can be accommodated under a smaller table top when disposed abovean underlying surface. This off-set distance is sufficient to keep thesupport legs of the opposing support pedestal from interfering with oneanother, thus allowing displacement substantially against the mountingsurface of the table top when disposed in the retracted position forstorage.

[0025] From the foregoing, it will be appreciated that the presentinvention provides a portable folding utility table that is durableenough to withstand increased wear and tear yet is light-weight for easyset up and take down. The present invention also provides a novel centersupport assembly that provides increased structural stability to thetable top with efficient design such that to allow the interrelation ofthe support pedestals. The center support assembly is also costeffective to manufacture and does not compromise the structuralintegrity of the table top. Further, the present invention provides autility table that facilitates a height that is comfortable for one ormore users to work at. The foregoing and other advantages and featuresof the present invention will become more fully apparent by examinationof the following description of the presently preferred embodiments andappended claims, taken in conjunction with the accompanying drawings.

[0026] These and other objects and features of the present inventionwill become more fully apparent from the following description andappended claims, or may be learned by the practice of the invention asset forth hereinafter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0033] It will be readily understood that the components of the presentinvention, as generally described and illustrated in the Figures herein,could be arranged and designed in a wide variety of differentconfigurations Thus, the following more detailed description of theembodiments of the assembly and method of the present invention, asrepresented in FIGS. 1 through 5, is not intended to limit the scope ofthe invention, as claimed, but it is merely representative of thepresently preferred embodiments of the invention.

[0034] The presently preferred embodiments of the invention will be bestunderstood by reference to the drawings, wherein like parts aredesignated by like numerals throughout.

[0035] One presently preferred embodiment of the present invention,designated generally at 10, is best illustrated in FIGS. 1 and 2. Asshown, with particular reference to FIG. 1, a utility table according tothe present invention is generally designated at 10. The utility table10 preferably includes a table top 12 having a mounting surface 14 and aworking surface 16 disposed opposite the mounting surface 14. In onepresently preferred embodiment, the table top 12 is supported by a firstsupport pedestal 18 and a second support pedestal 20. The first andsecond support pedestals 18, 20 may each comprise a first end 22attached to the mounting surface 14 of the table top 12.

[0036] Referring now to FIGS. 1 and 2, the utility table 10 of onepresently preferred embodiment includes a first pivotal support brace 24having a proximal end 26 attached to the first support pedestal 18 and adistal end 28 attached to the mounting surface 14. Similarly, a secondpivotal support brace 30 is shown having a proximal end 32 attached tothe second support pedestal 20 and a distal end 34 attached to themounting surface 14. The distal end 28 of the first pivotal supportbrace 24 may be disposed contiguous the distal end 34 of the secondpivotal support brace 30. The distal ends 28, 34 of the pivotal supportbraces 24, 30 are disposed in relation to a retaining assembly 36, whichmay be attached to the mounting surface 14. In one preferred embodiment,the retaining assembly 36 comprises a cross member.

[0037] As shown in FIG. 2, the utility table 10 includes a frame 40. Theframe 40 may comprise a first side rail 42 and an opposing second siderail 44. Preferably, the first side rail 42 is disposed substantiallyparallel the opposing second side rail 44, thereby providing a generallylongitudinal alignment therebetween. The first and second side rails 42,44 may be configured with a plurality of retaining apertures 46 tofacilitate attachment of the support pedestals 18, 20 and the crossbrace member 36 to the frame 40.

[0038] In one presently preferred embodiment, the mounting surface 14 ofthe table top 12 comprises opposing longitudinal interior side walls 48and opposing orthogonal interior side walls 52 disposed along aninterior periphery of the table top 12. The first and second side rails42, 44 may be secured to respective opposing longitudinal side walls 48,thus adding rigidity and strength to the structural integrity of tabletop 12. In one presently preferred embodiment, the side rails 42, 44 aresecured to the opposing longitudinal side walls 48 by fasteners. It willbe appreciated by those skilled in the art that the side rails 42, 44may be secured to the opposing longitudinal side walls 48 of themounting surface 14 using any number or variety of fasteners readilyknown in the art, such as, for example, screws, bolts, rivets,adhesives, or the like.

[0039] The cross-section of the side rails 42, 44 may be configuredhaving an S-shape. In one presently preferred embodiment, the side rails42, 44 may be attached to the respective longitudinal side walls 48, 50as to form respective channels 50 along the side rails 42, 44 betweenthe side rails 42, 44 and the longitudinal side walls 48 (See FIGS. 1and 2). In this configuration, the first end 22 of the support pedestals18, 20 may be positioned within opposing respective retaining apertures46 formed in the side rails 42, 44 abutting the longitudinal side walls48 within the channels 50, thereby substantially preventing lateralmovement of the support pedestals 18, 20 relative to the table top 12.Likewise, the cross brace member 36 may be positioned within opposingrespective retaining apertures 46 formed in the side rails 42, 44abutting the longitudinal side walls 48 within the channels 50, therebysubstantially preventing lateral movement of the cross brace member 36relative to the table top 12. In one presently preferred embodiment, thesupport pedestals 18, 20 and the cross brace member 36 are preferablydisposed substantially parallel to each other and in spaced-apartrelationship, wherein the cross brace member 36 is positioned betweenthe opposing support pedestals 18, 20. Still referring to FIG. 2, theframe 40 may also comprise a first end rail 54 and an opposing secondend rail 56. Preferably, the first end rail 54 is disposed substantiallyparallel to the opposing end rail 56. Each end rail 54, 56 has a firstend 58 and a second end 60 and is preferably positioned along theopposing orthogonal interior side walls 52 of the mounting surface 14 ofthe table top 12. In one presently preferred embodiment, the first end58 of each end rail 54, 56 is disposed within the channel 50 adjacentrespective ends 62 a, 62 b of the first side rail 42. Likewise, thesecond end 60 of each end rail 54, 56 is disposed within a channel 50adjacent respective ends 64 a, 64 b of the second side rail 44, therebyproviding a generally rectangular shape to substantially correspond withthe generally preferable rectangular shape of the table top 12.

[0040] In one presently preferred embodiment of the present invention,the first and second ends 58, 60 of respective end rails 54, 56 areconfigured with a tab member 66. The tab member 66 may be configured tofit within respective channels 50 beneath the retaining aperture 46 nearthe ends 62, 64 of the respective side rails 42, 44 with the utilitytable 10 in an upright position. It will be readily appreciated by thoseskilled in the art that, in this configuration, the tab members 66 actas levers with the support pedestals 18, 20 (positioned within thechannels 50 near the ends 62, 64 of the respective side rails 42, 44),thus acting as corresponding fulcrums. In this manner, the end rails 54,56 strengthen respective ends 68 a, 68 b of the table top 12, andprotect against bowing of the table top 12 at the ends 68 a, 68 b. Thefirst and second side rails 42, 44 in combination with the first andsecond end rails 54, 56 provide a means for structurally supporting thetable top 12, the support pedestals 18, 20, and the pivotal supportbraces 24, 30. In this configuration, lighter weight table tops 12 maybe used with this novel construction without losing rigidity orstructural integrity.

[0041] As will be appreciated, the end rails 54, 56 may interrelate tothe side rails 42, 44 in a variety of ways to provide structural supportfor the utility table 10 and help protect against bowing under variousloads that may be applied to the utility table 10 For example, the endrails 54, 56 may be welded to the side rails 42, 44. The end rails 54,56 may also be bonded to the side rails 42, 44 using a variety ofsuitable epoxies or resins. Further, the end rails 54, 56 and the siderails 42, 44 may be formed as a single unitary piece configured to thedesired size and shape. Moreover, it will be also appreciated that theend rails 54, 56 and the side rails 42, 44 need not interrelate at all,but could simply be attached to the respective interior opposing sidewalls 48, 52 of the mounting surface 14 of the table top 12.

[0042] In one presently preferred embodiment of the present invention,the frame 40 is formed of a substantially sturdy, rigid materialsufficient to provide structural integrity to the table top 12. Forexample, the frame 40 may be formed of metal. However, it will bereadily appreciated that the frame may be formed of a wide variety ofother suitable materials which are consistent with the spirit and scopeof the present invention. It will further be appreciated that the sizeand configuration of the frame 40 will depend, in part, on the size andconfiguration of the table top 12. Accordingly, the table top 12 and theframe 40 may be configured in a variety of shapes and configurations,including, but not limited to, a circle, polygon, square, rectangle,triangle, or any other suitable geometrical configuration.

[0043] Referring now to FIG. 3, the shape and size of the frame 40 isconfigured to generally conform to the periphery of the mounting surface14 of the table top 12. Specifically, in one presently preferredembodiment of the present invention, the frame 40 is attached inrelation to the mounting surface 14 by means of fasteners (not shown)which generally penetrate both the frame 40 and an adjacent point ofcontact of the mounting surface 14. As will be appreciated by thoseskilled in the art, a variety of other suitable means or methods forattaching the frame 40 to the mounting surface 14 of the table top 12may be employed, including, but not limited to, rivets, screws, bolts,glues, epoxies, or other bonding materials.

[0044] As can be best seen in FIGS. 2 and 3, the mounting surface 14 ofthe table top 12 is preferably configured to facilitate the attachmentof the frame 40 to the mounting surface of the table top 12, in onepresently preferred embodiment, the mounting surface 14 is configuredwith seats (not shown) positioned such that the end rails 54, 56 may bepositioned between respective opposing orthogonal interior walls 52 andthe seats (not shown). In this configuration, the end rails 54, 56 aresubstantially prevented from bowing inwardly toward the center of theutility table 10 under loads exerted upon the opposing ends of the tabletop.

[0045] It will be readily appreciated that the mounting surface 14 neednot have interior side walls 48, 52 at all to practice the teachings ofthe present invention. In this regard, the teachings of the presentinvention may be practiced without a frame 40 if the table top 12 issufficiently rigid. It will further be appreciated by those skilled inthe art that in the embodiments where there is 110 frame, the supportpedestals 18, 20 and cross brace member 36 may be attached to aninterior portion of the mounting surface 14. Further, in preferredembodiments where there are interior side walls 48, 52 but no frame 40,the support pedestals 18, 20 and cross brace member 36 may be positioneddirectly in retaining apertures (not shown) formed within the interiorside walls 48, 52 of the mounting structure 14 of the table top 12.

[0046] Referring back to FIG. 2, the support pedestals 18, 20 arepivotally attached to the mounting surface 14, thereby permitting eachof the support pedestals 18, 20 to be moved between a collapsedposition, in which each support pedestal 18, 20 lies flat insubstantially the same plane as the table top 12, and an extendedposition, in which each support pedestal 18, 20 is folded outward,substantially perpendicular to the plane of the table top 12.

[0047] Each support pedestal 18, 20 may include a pair of substantiallyparallel posts 80. Those of ordinary skill in the art will appreciatethat the teachings of the present invention can be practiced if eachsupport pedestal 18, 20 has more or less than two posts 80. Each pair ofposts 80 comprises a first end 82 and a second opposing end 84. In onepresently preferred embodiment, the first end 82 of each respective pairof posts 80 is secured to a cross pole 86. Respective ends 88 of eachcross pole 86 are preferably positioned within opposing retainingapertures 46 disposed within the opposing side rails 42, 44 of the frame40 such that the support pedestals 18, 20 may be disposed substantiallyparallel to each other. In this configuration, each cross pole 86rotates within respective pairs of retaining apertures 46 whenrespective pedestals 18, 20 move between the collapsed position and theextended position. In one presently preferred embodiment, a stabilizerarm 90 is preferably disposed between the respective pairs of posts 80to assist in structurally maintaining the spaced-apart relationship ofthe posts 80.

[0048] It will be appreciated by those skilled in the art that thesupport pedestals 18, 20 may be configured in a variety of ways suchthat to practice the teachings of the present invention. For example,the support pedestals 18, 20 may comprise a solid or integral piece orthe posts 80 may be curved in a different manner (e.g., see FIG. 3). Itwill further be appreciated by those of skill in the art that thesupport pedestals 18, 20 need not be in pivotal engagement with thetable top 12 to be collapsible. For example, the support pedestals 18,20 may simply be detachably engaged in relation to the table top 12 suchthat when it is desired to collapse the utility table 10 for storage,the support pedestals 18, 20 are removed from selective engagement withthe table top 12.

[0049] As stated above, the first and second support pedestals 18, 20are preferably connected to the table top 12 by means of the first andsecond pivotal support braces 24, 30, respectively. In one presentlypreferred embodiment of the present invention, the proximal ends 26, 32of the respective pivotal support braces 24, 30 are bifurcated tofacilitate pivotal engagement with the posts 80 of the respectivesupport pedestals 18, 20 as illustrated in FIGS. 1, 2, and 3. Thebifurcated proximal ends of the pivotal support braces 24, 30 eachpreferably comprise a pair of angled members 100.

[0050] Referring specifically to FIG. 2, the angled members 100 mayinclude a tab member 102 which pivotally engages and partially overlapsa corresponding tab member 104 adjacent each of the distal ends 28, 34of the pivotal support braces 24, 30, respectively, at an overlappingportion 106. When the support pedestals 18, 20 are in the extendedposition, the tabs 102 of the angled members 100 of the bifurcatedproximal ends 26, 32 are disposed substantially parallel to the tabs 104adjacent each distal end 28, 34 of the pivotal support braces 24, 30.When the support pedestals 18, 20 are in the collapsed position, thetabs 102 of the angled members 100 of the bifurcated proximal ends 26,32 are disposed substantially unparallel to the tabs 104 adjacent eachdistal end 28, 34 of the pivotal support braces 24, 30. The utilitytable 10 may include a pair of locking collars 108 which slidably engagerespective pivotal support braces 24, 30. The locking collars 108 arepreferably sized to fit over respective overlapping portions 106 of thepivotal support braces 24, 30 when the support pedestals 18, 20 are inthe extended position. With the locking collars 108 positioned overrespective overlapping portions 106, the bifurcated proximal ends 26, 32are prevented from moving relative to corresponding distal ends 28, 34of the pivotal support braces 24, 30, thus preventing the supportpedestal supports 18, 20 from being positioned in the collapsed positionwithout first disengaging the locking collars 108, respectively. It willbe appreciated by those skilled in the art that with the utility table10 in an upright position and the support pedestals 18, 20 in theextended position, the collars 108 may, under the force of gravity,position themselves about the overlapping portions 106. It will befurther appreciated that a variety of other locking mechanisms asassemblies may be utilized to lock the support pedestals 18, 20 in theextended position which are consistent with the spirit and scope of thepresent invention, including latches or other fasteners.

[0051] With reference now to FIG. 3, the utility table 10 is shownhaving an alternative configuration of the support pedestals 18, 20. Inthis alternate embodiment, each support pedestal 18, 20 comprises afirst member 114 pivotally engaged to the mounting surface 14 of thetable top 12 and a second member 116 configured for telescopingengagement with the first member 114, thereby permitting the height ofeach support pedestal 18, 20 to be selectively disposed at a pluralityof predetermined heights between a lengthened position and a retractedposition.

[0052] In one presently preferred embodiment, each first member 114 ofthe support pedestals 18, 20 includes a pair of outer members 118 eachhaving a proximal end 120 and a distal end 122. The proximal end of eachouter member 118 is connected to the table top 12 by means of the crosspole 86 to which they are preferably fixed (e.g., welded). The secondmember 116 of each support pedestal 18, 20 includes a pair of innermembers 124 each having a proximal end 126 and a distal end 128. Theproximal end 126 of the inner members 124 are configured in dimensionalsize and shape to engage the distal ends 122 of the outer members 118 intelescopic engagement. It will be appreciated by those of ordinary skillin the art that one or more stabilizer arms 90 may be employed tosupport the telescopic pedestals 18, 20.

[0053] Preferably, the inner members 124 and outer members 118 areseparated by a hard plastic bushing (not shown) to facilitate theslidable movement of the inner members 124 relative to the outer members118. Each bushing may be held in place with two small extensions thatextend through small holes (not shown) in the outer members 118. It willbe appreciated by those of skill in the art that there are a number ofways to facilitate the telescopic movement of the first member 114relative to the second member 116 of each support pedestal 18, 20.

[0054] In the preferred embodiment illustrated in FIG. 3, the supportpedestals 18, 20 include means for locking the support pedestals 18, 20in preselected positions between the retracted position and thelengthened position. At least one of the inner members 124 is configuredwith a first hole 134. A corresponding outer member 118 may beconfigured with at least one hole 136 and preferably a plurality ofholes 136 positioned such that at a preselected table top 12 height thefirst hole 134 in the inner member 124 may be aligned with a second hole136 in the outer member 118. In one presently preferred embodiment, asnap pin mechanism 138 may be positioned adjacent the first hole 134within the inner member 124 such that the pin 138 is biased outwardlythrough the aligned holes 134, 136, thereby locking the inner and outermembers 118, 124 of the support pedestals 18, 20 in a preselectedposition. By supplying sufficient force to the pin mechanism 138, it maybe disengaged and removed from the hole 136 in the outer member 118,thereby permitting relative movement between the inner 124 and outer 118members of the support pedestals 18, 20 and allowing the supportpedestals 18, 20 to be selectively raised or lowered. It will beappreciated by those skilled in the art that a variety of otheradjustment mechanisms as assemblies known in the art for locking thefirst and second support pedestals 18, 20 in an extended position may beutilized and are herein incorporated.

[0055] As best shown in FIGS. 1, 2, and 3, the distal ends 28, 34 ofeach pivotal support brace 24, 30 are engageably secured to theretaining assembly 36 (e.g., cross brace member). In one presentlypreferred embodiment of the present invention, the distal ends 28, 34 ofeach pivotal support brace 24, 30, respectively, are pivotally attachedto the retaining assembly 36. Each of said distal ends 28, 34 areconfigured with an opening 142 having an interior periphery sufficientfor engaging at least a portion of the linear length of the cross-bracemember 36.

[0056] It will be appreciated by those skilled in the art that theretaining assembly 36 generally provides structural support to thecenter of the table top 12 of the utility table 10. It will further beappreciated that with the distal ends 28, 34 attached contiguous eachother in retention to the cross brace member 36 forces applied to thetable top 12 which would ordinarily be transferred through one of thesupport pivotal braces 24, 30, respectively, into the table top 12causing it to bow, will substantially be nullified by the counter forceprovided by the opposing pivotal support brace 24, 30, respectively.

[0057] For example, the horizontal component of a force applied by auser at one end 68 a of the table top 12 will act upon the pivotalsupport brace 18 and, because the distal ends 28, 34 of the pivotalsupport braces 24, 30, respectively, are attached to the retainingassembly 36, an equal and opposite horizontal force component applied bythe other pivotal support brace 20 will substantially cancel out thehorizontal component of the original force. Accordingly, the presentinvention provides increased structural support to the table top 12 withfewer parts. As will be appreciated by those skilled in the art, theretaining assembly 36 can be disposed in a variety of configurationswhich are consistent with the spirit and scope of the present inventionso as to allow the pivotal support braces 24, 30 to supportablyinterrelate with each other. Such alternative configurations arediscussed below.

[0058] With reference to FIGS. 1, 2, and 3, the table top 12 ispreferably formed of a blow-molded plastic, and specifically, highdensity polyethylene. It will be appreciated by those of skill in theart, however, that the table top 12 may be formed of a variety of othersufficiently sturdy materials such as, plywood, particle board, solidwood, wood slates, metal alloys, fiberglass, ceramics, graphite, any ofnumerous organic, synthetic or processed materials, includingthermoplastic or thermosetting polymers of high molecular weight with orwithout additives, such as, plasticisers, auto oxidants, extenders,colorants, ultraviolet light stabilizers, or fillers and/or othercomposite materials.

[0059] Referring back to FIG. 1, in one presently preferred embodimentof the present invention, the working surface 16 of the table top 12 maybe smooth or, in the alternative, textured, if desired. In addition, theworking surface 16 may comprise an outer periphery 144 having at least aportion 146 which is beveled to increase the comfort of a person restingtheir arms against the edges of the table top 12. In one presentlypreferred embodiment, the entire outer periphery 144 of the workingsurface 16 of the table top 12 is beveled. The height of the blow-moldedtable top 12 of one presently preferred embodiment is about fivecentimeters, the thickness of any pan 13 of the blow-molded table top 12is preferably about one-half of a centimeter to about three-quarters ofa centimeter.

[0060] Referring now to FIGS. 2 and 3, the mounting surface 14 mayinclude at least one mounting member 148. Preferably, a pair of mountingmembers 148 are attached to the mounting surface 14 to receive andretain the cross brace member 36 of the retaining assembly. In onepresently preferred embodiment, each mounting member 148 includes arecess or groove 150 configured with a corresponding size and shapesufficient to retain the cross brace member 36 therein. For example, thecross brace member 36 may snap fit into the recess or groove 150 of themounting member 148.

[0061] Additionally, the mounting surface 14 of the table top 12 mayfurther include one or more securing members 152 for securing each ofthe support pedestals 18, 20, respectively. Preferably, a pair ofsecuring members 152 are disposed in relation to the mounting surface 14for releasably securing a respective support pedestal 18, 20 in thecollapsed position adjacent the mounting surface 14. Each securingmember 152 is generally configured and disposed relative to the mountingsurface 14 such that when the support pedestals 18, 20 are in thecollapsed position, at least one securing member 152 frictionallyengages a support pedestal post 80 such that the support pedestals 18,20, respectively, may be maintained in the collapsed position, asillustrated in FIG. 3. In one presently preferred embodiment of thepresent invention, a pair of securing members 152 are offset on opposingsides of a single support pedestal post 80 for securing each of thesupport pedestals 18, 20, respectively, in the collapsed position. Itwill be apparent that other mechanisms may be constructed in accordancewith the inventive principles set forth herein for securing the supportpedestals 18, 20 in the collapsed position. It is intended, therefore,that the examples provided herein be viewed as exemplary of theprinciples of the present invention, and not as restrictive to aparticular structure for implementing those principles.

[0062] Referring now to FIGS. 2 and 3, a first manifold 154 and a secondmanifold 156 are preferably disposed at opposing ends 68 a, 68 b of thetable top 12. The manifolds 154, 156 provide additional support for theends 68 a, 68 b of the table top 12 and assist in facilitating the blowmolding process by providing a means for uniformly dispersing air downthe length of the table top 12. The mounting surface 14 of the table top12 may also include a plurality of depressions 158 (e.g., kiss-offs)which tend to add structural support and integrity to the table top 12.In one presently preferred embodiment, these depressions 158 areuniformly distributed through out the mounting surface 4 of the tabletop 12.

[0063] The structural features of the table top 12, including thebeveled edges and/or textured working surface 16, the mounting members148, the securing members 152, the manifolds 154, 156, and thedepressions 158 may be integral with the table top 12 and may be formedby means of a corresponding mold and blow-molding process. It will beappreciated by those skilled in the art that there are alternative waysto create and attach these features. For example, the mounting members48, securing members 152, and manifolds 154, 156 may be separate piecesthat are attached to the mounting surface 14 by adhesive bonding or theuse of conventional fasteners. Likewise, the texturing and/or bevelingof the edges of the working surface of the table top and theintroduction of depressions into the mounting surface may also beaccomplished after the table top 12 is molded by a variety ofconventional methods readily known in the art.

[0064] As discussed above, the table top 12 includes an outer periphery144 and a portion 146 of the outer periphery may be beveled, forexample, to increase the comfort of a person resting their arms againstthe table 10. As shown in the accompanying figures, the table top 12 mayalso include an outer lip 159 that is generally disposed about the outerperiphery 144 of the table top 12. Preferably, the lip 159 forms atleast part of an outer edge or boundary of the table top 12. One skilledin the art will appreciate that the lip 159 does not have to create theouter edge of the table top 12 and the lip can extend around all or onlya portion of the table top 12.

[0065] The table top 12 and lip 159 are preferably integrally formedduring a blow-molded process to create a unitary, one-piece structure.Advantageously, the integral, one-piece table top 12 and lip 159 mayassist in creating a solid and sturdy table 10. For example, because thetable top 12 and lip 159 are preferably formed as part of an integralstructure, there are no connections or attachments that can break orfail. Additionally, the integral formation of the table top 12 and lip159 may increase the strength and structural rigidity of the table top.Further, the integral formation of the table top 12 and lip 159 maycreate a more cost-effective table 10 because the lip does not have tobe subsequently attached or connected. Finally, the one-piece table top12 and lip 159 may form a very comfortable, lightweight, and usefultable top because no connections are required and no sharp edges areexposed. It will be appreciated, however, that the table top 12 and lip159 may be formed by separate pieces that are subsequently attached byany suitable mechanism or method such as fasteners, adhesives, and thelike. It will also be appreciated that the table top 12 and lip 159 canbe constructed or manufactured by any suitable process or mechanism.

[0066] The lip 159 is preferably disposed about the outer periphery 144of the table top 12 and at least a portion of the lip extends in anopposite direction from the upper or working surface 16 of the tabletop. For example, as best seen in FIGS. 2 and 3, the lip 159 may extenddownwardly or outwardly from the underside of the table top 12. Inparticular, the lip 159 may include an upper portion that is disposedproximate the working surface 16 and an opposing lower portion. Theupper portion of the lip 159 is preferably aligned with the workingsurface 16 of the table top 12 to create a generally planar surface, butthe upper portion may also be located above or below the working surfaceof the table top. The lower portion of the lip 159 extends beyond orpast the mounting surface 14 of the table top 12. The lip 159 preferablyhas a height of about five centimeters measured from the upper portionto the lower portion, but the lip can have any suitable heightdepending, for example, upon the size and configuration of the table 10.

[0067] The upper portion of the lip 159, on the other hand, may bedisposed proximate the mounting surface 14 of the table top 12 and thelower portion of the lip extend beyond or past the mounting surface ofthe table top. Thus, in this configuration, the lip 159 protrudesdownwardly from the mounting surface 14 of the table top 12 and theheight of the lip is the distance from the mounting surface to the lowerportion of the lip. The lip 159 preferably has a height of about fivecentimeters measured from the mounting surface 14 to the lower portion.One skilled in the art, however, will appreciate that the lip 159 canhave any suitable size and/or configuration depending, for example, uponthe intended use of the table 10.

[0068] As best seen in FIGS. 1, 2 and 3, the lip 159 includes an outersurface and an inner surface. The outer surface of the lip 159preferably forms at least a portion of the periphery 144 of the tabletop 12 and all or a portion of this outer periphery may be beveled 146.As shown in the accompanying figures, the outer surface of the lip 159may also be contoured to include one or more steps or ledges.Preferably, these steps or ledges create a graduated or divided outersurface that may extend outwardly and/or inwardly relative to the tabletop 12. For example, as shown in FIG. 1, the lip 159 may include anupper beveled surface, a series of three or more steps or ledges, and alower beveled surface. The upper steps preferably extend outwardly fromthe table top 12 and the lower steps preferably extend inwardly to forma somewhat rounded or curved outer surface of the lip 159. It will beappreciated that the lip 159 can have any suitable configuration such asa plurality of steps, ledges or ridges; a curved, straight, slanted orsloped outer surface; or a combination of straight, slanted or curvedsurfaces. Additionally, all or only a portion of the lip 159 may have acontoured surface and the contoured surface may also be configured tohelp increase the strength or structural integrity of the table top.

[0069] The inner surfaces of the lip 159 form the interior side walls48, 52 and, as discussed above, the interior side walls may be used tosecurely attach the frame 40 to the table top 12. As shown in theaccompanying figures, the interior side walls 48, 52 extend from themounting surface 14 of the table top 12 to the lower portion of the lip.Thus, the interior side walls 48, 52 have a height extending from themounting surface 14 to the lower portion of the lip 159. As best seen inFIGS. 2 and 3, the inner surfaces of the lip 159 have a height that isgenerally equal to or less than the height of the outer portions of thelip.

[0070] In greater detail, as seen in FIGS. 2 and 3, the inner surfacesof the lip 159 that extend longitudinally along the length of the tabletop 12 are preferably sized and configured to receive the first siderail 42 and second side rail 44 of the frame 40. The inner surfaces ofthe lip 159 that extend orthogonally along the ends of the table top 12are preferably sized and configured to receive the first end rail 54 andsecond end rail 56 of the frame 40. Desirably, as shawn in FIG. 1 theheights of the inner surfaces of the, lip 159 are generally equal to orgreater than the height of the frame 40 so that the frame is generallyhidden from view when the table 10 is being used or ready for use. Inparticular, the inner surfaces of the lip 159 that extend longitudinallynear the edges of the table top 12 desirably have a height that isgenerally equal to or greater than the height of the first and secondside rails 42, 44 of the frame 40 so that this portion of the frame isgenerally hidden from view. Additionally, the inner surfaces of the lip159 that extend orthogonally near the ends of the table top 12 desirablyhave a height that is generally equal to or greater than the height ofthe first and second end rails 54, 56 of the frame 40 so that thisportion of the frame is generally hidden from view. Thus, the lip 159can be configured to generally hide the frame 40 when the table 10 isviewed from a plane that is generally aligned with or above the tabletop 12.

[0071] Advantageously, because the frame 40 may be completely orgenerally hidden from view, the frame does not have to be finished andmay contain visible imperfections or flaws. For example, the frame 40may have one or more exposed welds, rough edges, sharp surfaces,unpainted surfaces, gaps, openings, and the like, but these portions ofthe frame may be hidden from view and/or covered by the lip 159 of thetable top 12. Significantly, this may decrease the cost to manufacturethe table 10 because at least a portion of the frame 40 may not have tobe finished and/or may contain superficial or readily apparent blemishesor imperfections. Further, because the lip 159 may hide all or a part ofthe connection or attachment of the frame 40 to the table top 12, thatmay create a more aesthetically pleasing table 10. The lip 159 may alsohide all or a portion of the pivotal connection of the first and secondsupport pedestals 18, 20 to the mounting surface 14 of the table top 12.It will be appreciated, however, that the lip 159 does not have to coveror hide the frame 40 from view, and all or a portion of the frame 40 maybe visible or exposed.

[0072] As best illustrated in FIG. 1, when the utility table 10 isdisposed in an upright position in relation to an underlying surface andthe support pedestals 18, 20 extended with the collars 108 placed overthe overlapping portions 106 of the respective pivotal support braces24, 30, the utility table 10 of the present invention is positioned foruse. When a user desires to collapse the utility table 10 for storage,one presently preferred method for doing so is to invert the utilitytable 10, as shown in FIG. 3. With the utility table 10 in the invertedposition, the collars 108 may be slid away from engagement with theoverlapping portion 106 of the respective pivotal support braces 24, 30.This allows the support pedestals 18, 20 to be folded inwardly towardthe table top 12 into the collapsed position. With the support pedestals18, 20 in the collapsed position, the utility table 10 can easily bemoved and stored.

[0073] With reference now to FIG. 4, another presently preferredembodiment of the utility table of the present invention is generallydesignated at 210. In this embodiment, the utility table 210 includes atable top 12 having a mounting surface 14 and a working surface 16disposed opposite the mounting surface 14. A first support pedestal 18and a second support pedestal 20 are pivotally attached to the mountingsurface 14 of the table top 12. Preferably, the first and second supportpedestals 18 20 are independently attached to a support bar 212 havingopposing ends 211 configured to engage receiving apertures 46 formed inopposing side rails 42, 44 of a rigid flame 40 supportably disposed inrelation to the table top 12.

[0074] In one presently preferred embodiment, the support bar 212 isconfigured having a bend formed at its opposing ends 211 to ensure thatthe first and second support pedestals 18, 20, respectively, foldproperly against the mounting surface 14 of the table top 12 whendisposed in the collapsed position As appreciated, the slight bendformed at the opposing ends 211 of the support bar 212 has thestructural effect of extending the central portion of the support bar212 away from the axis of rotation of the support bar 212 relative tothe frame 40. Moreover, the bending configuration of the support bar 212at its opposing ends 211 provides additional safety, in proportion tothe weight applied against the table top 12, by maintaining the firstand second support pedestals 18 and 20 in the extended position

[0075] The support bar 212 may be omitted from engagement with theproximal end 120 of the support pedestals 18, 20 in favor of a suitableattachment assembly designed to facilitate pivotal engagement betweenthe support pedestals 18, 20 and the mounting surface 14 of the tabletop 12. Those skilled in the art will readily recognize other possiblemodifications and adaptations which are consistent with the spirit andscope of the present invention and which are herein contemplated by thepresent invention.

[0076] Still referring to FIG. 4, the utility table 210 of the presentinvention may include each first member 114 of the support pedestals 18,20 having a pair of outer members 118 each having a proximal end 120 anda distal end 122. The proximal end of each outer member 118 is connectedto the table top 12 by means of the support bar 212 to which they arepreferably fixed (e.g., welded). The second member 116 of each supportpedestal 18, 20 includes a pair of inner members 124 each having aproximal end 126 and a distal end 128. The proximal end 126 of the innermembers 124 are configured in dimensional size and shape to slidablyengage the distal ends 122 of the outer members 118 in telescopicengagement.

[0077] Preferably, the inner members 124 and outer members 118 areseparated by a hard plastic bushing (not shown) to facilitate theslidable movement of the inner members 124 relative to the outer members118. Each bushing may be held in place with two small extensions thatextend through small holes (not shown) in the outer members 118. It willbe appreciated by those of skill in the art that there are numerous waysto facilitate the telescopic movement of the first member 114 relativeto the second member 116 of each support pedestal 18, 20 which arereadily contemplated herein. It is also contemplated herein that thelength of the support pedestals 18, 20 may be fixed and, thus notselectively adjustable to a plurality of heights.

[0078] As illustrated in FIG. 4, an elongated foot member 213 may berigidly attached at the distal end 128 of each of the inner members 124of the support pedestals 18, 20 so as to provide additional stability tothe table top 12 when disposed in the upright position.

[0079] Preferably, the foot member 213 facilitates a more evendispersion of the supportable weight of the utility table 210 over agreater portion of the underlying surface in addition, because thelength of the foot member 213 tends to span the distance between thefirst and second members 114, 116, one or more stabilizer arms 90 may beunnecessary.

[0080] Similar to the preferred embodiments of the utility tableillustrated in FIGS. 1-3, the utility table 210 includes a first pivotalsupport brace 224 having a bifurcated proximal end 226 attached to thefirst support pedestal 18 and a distal end 228 pivotally attached to afirst retaining assembly 36 a. Similarly, a second pivotal support brace230 having a bifurcated proximal end 232 attached to the second supportpedestal 20 and a distal end 234 pivotally attached to a secondretaining assembly 36 b. In one presently preferred embodiment, each ofthe retaining assemblies 36 a, 36 b comprise a cross-brace member havingopposing ends and an intermediate body portion formed therebetween. Eachof the distal ends 228, 234 of the pivotal support braces 224, 230 areconfigured with openings 242 having an internal periphery sufficient forengaging at least a portion of the length of the intermediate bodyportion of the cross-brace members 36 a, 36 b, respectively.

[0081] The opposing ends of the first and second cross-brace members 36a, 36 b, respectively, are configured so as to be introduced andretained within corresponding retaining apertures 46 formed in opposingside rails 42, 44 of the frame 40 or, in the alternative, withinopposing, interior side walls of the table top 12. Preferably, the firstand second cross-brace members 36 a, 36 b are separated by a centralportion 216 of the table top 12. Structurally, this central potion 216of the table top 12 must have sufficient structural integrity to supporta compressive load, either through the frame 40, the entire surface ofthe table top 12, or by some combination of the two, when weight isapplied against the table top 12 to avoid bowing.

[0082] The dual cross-brace supportable configuration of the utilitytable 210 of the present invention is advantageous because the pivotalsupport braces 24, 30 obstruct less of the available space beneath thetable top 12 and between the support pedestals 18, 20 Consequently, moreroom is available to accommodate the legs of one or more users beneaththe table top 12, thereby making the utility table 210 more comfortableto users. Furthermore, the absence of the cross-brace members 36 a, 36 bfrom the central portion 216 of the table top 12 provides usable storagespace to accommodate the foot members 213 when the support pedestals 18,20 are disposed in the collapsed position. As will be appreciated bythose skilled in the art, the central portion 216 integrally formed inthe mounting surface 14 of the table top 12 may be configured having awider or narrower dimension than illustrated by way of example in FIG.4, depending on the overall extended length of the table top 12, thesupportable weight the table top is designed to bear, the size of thefoot members 213, and/or the need for usable space beneath the table top12 when the utility table 210 is disposed in the usable position.

[0083] In one presently preferred embodiment, a pair of locking collars217 is provided which slidably engage respective overlapping portions ofthe pivotal support braces 224, 230. The locking collars 217 arepreferably configured and sized such that when the support pedestals 18,20 are selectively disposed in the extended position, the lockingcollars 217 may be engageably positioned in relation to the overlappingportions to prevent the bifurcated proximal ends 226, 232 from movingrelative to the corresponding distal ends 228, 234 of the pivotalsupport braces 224, 230, thus preventing the support pedestal supports18, 20 from being positioned in the collapsed position without firstdisengaging the locking collars 217, respectively.

[0084] As with the previous preferred embodiments illustrated in FIGS.1-3, a plurality of kiss-offs 218 may be formed in the mounting surface14 of the table top 12 to add structural integrity and strength to theworking surface 16 of the blow molded table top. In addition, aplurality of plateaus 219 and longitudinal trenches 220 may also beformed in the mounting surface 14 to further add stiffening and strengthto the table top 12. Correspondingly, these plateaus 219 and trenches220 operably function to increase the section modulus of the table top12 by moving material away from the neutral axis of the table top 12,thus making it more difficult to bend the table top 12 in a longitudinaldirection, as when a heavy load is positioned in the middle of the tabletop 12. As will be appreciated, the kiss-offs 218 may be formed withinthe trenches 220 to ensure that the table top 12 can be made hollowwithout concern that the working surface 16 may have a tendency to flexinwardly toward the mounting surface 14 when a weight is placed on thetable top 12.

[0085] Additionally, an opening 222 may be formed in the table top 12 toprovide means for introducing a support pole of an umbrella assembly(not shown) or the like. Although certain structural elements andcomponents, such as: (1) one or more stabilizer arms 90 engageablydisposed in relation to the first and second member 114, 116 of thesupport pedestals 18, 20 (see FIGS. 2 and 3); (2) one or more mountingmembers 148 for supportably retaining the retaining assembly 36 inrelation to the mounting surface 14 of the table top 12 (see FIGS. 2 and3); (3) one or more securing members 152 attached to the mountingsurface 14 of the table top 12 for securing the support pedestals 18, 20in the collapsed position (see FIGS. 2 and 3); (4) one or more manifolds154, 156 that assist in facilitating the blow molding process byproviding for uniform dispersion of air along the length of the blowmolded table top 12 (see FIGS. 2 and 3); and (5) beveled edges and/or atextured working surface 16 (see FIG. 1) have been omitted from theembodiment of the utility table 210 illustrated in FIG. 4. It iscontemplated herein that one or more of these structural features,however, may be incorporated into the alternate design of the utilitytable 210, if desired.

[0086] With reference now to FIG. 5, another presently preferredembodiment of the utility table of the present invention is (generallydesignated at 310. As shown, the utility table 310 includes a table top12 having a mounting surface 14 and a working surface 16 disposedopposite the mounting surface. Structurally, the table top 12 ispreferably supported above an underlying surface by a first supportpedestal 18 and a second support pedestal 20 disposed at spaced-apartrelationship to the first support pedestal. Both the first and secondsupport pedestals 18, 20 are preferably attached to the mounting surface14 or, in the alternative, to a rigid support frame 40. A first pivotalsupport brace 324 includes a proximal end 326 pivotally attached to thefirst support pedestal 18 and a distal end 328 pivotally attached to aretaining assembly 36. Similarly, a second pivotal support brace 330 isshown having a proximal end 332 pivotally attached to the second supportpedestal 20 and a distal end 334 pivotally attached to the retainingassembly 36 As will be appreciated, the distal ends 328, 334 of thefirst and second pivotal support brace 324, 330, respectively, maypivotally attached to the mounting surface 14 by means of a engagingbracket (not shown).

[0087] Because the alternate preferred embodiment of the utility table310, as illustrated in FIG. 5, is substantially similar in constructionto the utility table 10 shown in FIGS. 1-3, only those structuralvariations which exist between these two embodiments will be furtherdisclosed hereinbelow.

[0088] Specifically, one presently preferred embodiment of the utilitytable 310 includes a first support pedestal 18 having two support legs312, 314. Each of the support legs 314. 312 of the first supportpedestal 18 may be formed having a proximate end 316 rigidly attached toa cross pole 86 mounted in pivotal relation to the frame 40 or, in thealternative, to the mounting surface 14 of the table top 12 independentof the other leg. Similarly, each of the support legs 314, 312 of thesecond support pedestal 20 may be formed having a proximate end 316rigidly attached to a cross pole 86 mounted in pivotal relation to theframe 40 or, in the alternative, to the mounting surface 14 of the tabletop 12 independent of the other leg.

[0089] To accommodate a table top 12 having a length that is smallerthan the fixed or extendable length of the legs 312, 314 of the supportpedestals 18, 20, the relative disposition of the distal ends 318 ofeach of the support legs 312, 314 of the first support pedestal 18 areoffset from the corresponding distal ends 318 of each of the supportlegs 312, 314 of the second support pedestal 20 disposed on an oppositeside of the table top 12. The distal end 318 of the first support leg312 of the first support pedestal 18 is offset in a lateral direction320 from the second support leg 314 of the first support pedestal.Similarly, the distal end 318 of the first support leg 312 of the secondsupport pedestal 20 is offset in a lateral direction 320 from the secondsupport leg 314 of the second support pedestal 20. This offsetconfiguration enables the use of a smaller table top 12 and frame 40because the support pedestals 18, 20 can include a length greater thanthe distance between the opposing ends of the table top 12, and yetstill fold into a parallel configuration relative to the mountingsurface 14 of the table top 12 without interference by the distal ends318 of each of the support legs 312, 314 of the first and second supportpedestals 18, 20.

[0090] The foregoing function can be structurally accomplished in avariety of ways. For example, both the proximal and distal ends 316, 318of the support legs 312, 314 may be laterally offset so that the legs312, 314 are always parallel to the frame 40, as shown in FIG. 5.Alternatively, the proximal ends 316 may remain aligned in the foldedposition, and the legs 312, 314 may fold at an angle. This may be doneby pivotally mounting the proximal ends 316 to the mounting surface 14at an angle, or by mounting the cross pole 86 at a diagonal angle withrespect to the frame 40 and table top 12.

[0091] As discussed above, the retaining assembly 36 generally providesstructural support to the center of the table top 12 of the utilitytable 310. It will be further appreciated that with the distal ends 328,334 attached contiguous each other in retention to the cross-bracemember 36, forces applied to the table top 12 which would ordinarily betransferred through one of the support pivotal braces 324, 330,respectively, into the table top 12 causing it to bow, willsubstantially be nullified by the counter force provided by the opposingpivotal support brace 324, 330, respectively.

[0092] For example, the horizontal component of a force applied by auser at one end of the table top 12 will act upon the one of the supportpedestals 18, 20 and, because the distal ends 328, 334 of the pivotalsupport braces 224, 330, respectively, are attached to the retainingassembly 36, an equal and opposite horizontal force component applied bythe other pivotal support brace 18, 20 will cancel out the horizontalforce component of the original force. Accordingly, although the supportlegs 212, 214 of the support pedestals 18, 20 are offset, the structuralconfiguration of the present invention provides increased structuralsupport to the table top 12 with fewer parts. As will be appreciated bythose skilled in the art, the retaining assembly 36 may be disposed in avariety of configurations which are consistent with the spirit and scopeof the present invention so as to slow the pivotal support braces 324,330 to supportably interrelate with each other. Moreover, the utilitytable 210 shown in FIG. 4 and discussed in detail hereinabove, mayinclude support pedestals 18, 20 that comprise spaced apart support legswhich are offset from the corresponding support legs of the opposingsupport pedestal to provide the advantages of overlapping the legs, ifdesired.

[0093] Although certain structural elements and components, such as: (1)telescoping support legs operable to adjust the height of the table top12 above an underlying surface, (2) a second cross-brace member 36 bformed independent of a first cross-brace member 36 a (see FIG. 4); (3)a plurality of kiss-offs 158 formed in the mounting surface 14 of thetable top 12 (see FIGS. 2 and 3), (4) one or more mounting members 148for supportably retaining the retaining assembly 36 in relation to themounting surface 14 of the table top 12 (See FIGS. 2 and 3), (5) one ormore securing members 152 attached to the mounting surface 14 of thetable top 12 for securing the support pedestals 18, 20 in the collapsedposition (see FIGS. 2 and 3); (6) one or more manifolds 154, 156 thatassist in facilitating the blow molding process by providing for uniformdispersion of air along the length of the blow molded table top 12 (seeFIGS. 2 and 3); (7) a bend formed in the opposing ends 211 of thesupport bar 212 (see FIG. 4); (8) beveled edges and/or a texturedworking surface 16 (See FIG. 1); and (9) a plurality of plateaus 219 andlongitudinal trenches 220 may also be formed in the mounting surface 14to further add stiffening and strength to the table top 12 (see FIG. 4)have been omitted from the embodiment of the utility table 310illustrated in FIG. 5. It is contemplated herein that one or more of theforegoing structural however, may be incorporated into the design of theutility table 310, if desired.
